4 Claims. (Cl. 189-66) This invention relates to window ventilator andscreen constructions particularly of extruded metal frame and sash typeswherein the frame is especially well adapted for mounting in walls ofblock construction, preferably during erection, and wherein small unitsof such window ventilator and screen constructions with movable sashesprovide screened ventilators in walls built of glass blocks, forexample.

A primary object of the present invention is to provide an improvedwindow construction of such units particularly with respect to theopening of the sash from a closed locked position, in a window frame inwhich a weathertight seal is maintained, to an elevated and inwardlytilted position permitting Ventilating air to pass both under thc loweredge of the sash frame and over the upper edge thereof, following theupwardly sloping wall provided by the` sash.

Another object of the invention is to provide improved mounting meansfor the sash which yieldably holds the sash in any desired slopingposition to control the ventilating air passage and to provide alimiting gripping stop for the sash when it is opened to the fullestextent.

An additional obiect of the invention is to provide such mounting meansincluding detachable pivot members for swingably mounting the sash frameupon the v/indow frame,` yieldable spring mounting members for slidablyattaching the sash frame tothe Window frame, locking or latchingelements and the like so that the sash will be retained in an effectivemanner by window frame in both closed and any open positions of thesash.

A further object of the invention is to provide such a constructionwherein the frame is formed preferably of extruded parts to provide forboth the mounting of the movable and swinging sash therein and of ascreen adjacent the outer side of the frame with a water shed above thescreen support, and means for locking the screen to the frame in a lowerportion of the frame.

In addition, an object of the invention is to provide an improved framesill and associated sash frame construction whereby the entrance ofwater, moisture, cold air and dust is minimized.

` Furthermore, an object is to provide means whereby the sash frame maybe readily inserted into the window frame without any disassembling ofthe latter.

Yet another object is to provide a resilient connection of the sidemembers of the sash frame and side jambs of the window frame, wherebythe sash frame will not be apt to stick due to expansion of the membersand jambs.

A further object is to provide an effective weatherstripping meanscarried by the sash frame side and head members.

Additionally, an object is to provide a window construction in whichmost of the framing parts are of extruded metal, particularlylight-weight metal which re quires no protective coating.

Moreover, an important object is to provide framing parts of extrudedmetal, connected by the employment of novel connecting means with a viewto reducing the Patent "ice expense of construction yet providing astrong assembly which is also especially precise as to dimensions andthe angularity of the framing parts, one with respect to another.

Further` objects and features of our improved construction will appearin the following detailed description of a highly satisfactoryconstruction of our invention as illustrated in the accompanyingdrawings forming a part of this specification.

Fig. l() is a fragmentary elevation of the outer face of the sash.

In the drawings, wherein, for the purpose of illustration, isillustrated a preferred embodiment` of the invention and wherein similarreference characters designate corresponding parts throughout theseveral views, the letter A designates the window construction and Bdesignates a wall into which the Window construction is set.

The window construction A includesa window frame 10, sash frame` l1 withglass 12 and screen 13 all constructed of a size particularly desirablefor ventilation in a wall B composed of glass blocks 9S; the window inthis instance being polygonal, three blocks wide and of the same height.While the construction is particularly adapted for ventilators in suchglass block walls the invention is equally adaptable for other sizes andinstallation in other wall structures.

The window frame iti comprises extruded metal sill 14, lintel l5, andside jambe i6 comprising three forms of extruded metal strips.. Each ofthese strips has a main transverse wall i7 for the sill 14, 18 for thelintel 15 and 19 for the side jambs 16, the widths of which are in accordance with the thickness of the wall B. Each strip also has an innertlange 2i? extending from the respective Walls 17, 18 and 19 and theanges may be provided with grooves 2 or the like formed therein in theextrusion process as an ornamental trim for the window frame innercasing. The sill 14 and side jambs i6 are formed in the extrusionprocess each with an outer flange 22. The flanges 2li and 22 on the silland jambs, with their respective transverse walls, provide'outwardlyextending channels which face adjacent portions of the wall B into whichthe window construction A is set during fabrication of the f wall B; ofcourse itis obvious that if either of 'thes'etsetjs of flanges wereseparate and provided With any conveni Y tional form of securing meansto secure them to the sill, lintel and side jambs the windowconstruction could be applied in a nished wall and secured in place witha surrounding liner 96, usual mortar cementing material 97 and caulking98 which seals the joints between the frame il@ and wall B. Y

Instead of an outer flange 22, the transverse wall 18 of lintel 15 isformed with an outwardly sloping water shed 24 terminating in adownwardly extending lip flange 25. This wall 18 also has a downwardlyextending flange 26 spaced inwardly of the ilange 25, and from the outersurface of which a preferably small outwardly extending horizonal flange27 extends with an upwardly extending ange 28 terminatingin a roundedportion 29. These latter two parts provide a pivot support means underthe water shed 24 for the frame of the screen 13.

Transverse wall 17 of sill 14 has an upwardly extending ange 30 disposedinwardly of the flange 20 and spaced inwardly of the flange 3th is anupwardly extending flange 31 substantially paralleling the former andthe space between the two flanges 30 and 31 provides room for opening ofthe window as will be explained hereinafter and also for the receptionof any precipitation from the sash so that it will ilow to the exteriorof the window frame instead of inwardly. The upper portion of the flange31 is stepped, providing shoulders for abutment by portions of the sashframe to be described. At the base of the flange 31 may be providedspaced apart weep holes 32 for the exit of precipitation. It will beseen that sill 14 includes the wall 17, downwardly extending flanges 20and 22, and upwardly extending flanges 30 and 31, all extruded as anintegral strip.

The lintel 15 and side jarnbs 16 each includes an inwardly projectingflange 33, which is engaged by the outer surface of the frame 11 of thesash when the sash is closed, and a narrow, inwardly projecting flange34, paralleling flange 33, which engages a portion of the frame of thesash 11 and provides a weathertight seal therewith when the sash frameis closed. Thus the lintel 15 includes the transverse wall 18, an innerflange 20, outside water shed 24 and screen supporting ilange 26 withits pivot means 27, 28 and 29, and two sash frame engaging flanges 33and 34. The side jambs 16 each consist of a transverse wall 19, insideand outside trim and channel forming flanges 20 and 22 and sash engagingflanges 33 and 34.

In fabricating the sill 14, lintel 15, and side jambs 16 into a windowframe 10, the extruded strips are cut to the required lengths,transverse walls 17 and 18 are preferably reduced in length by havingtheir end portions cut away so that their reduced ends 35, as shown inFig. 3, extend only slightly between the flanges 20 and 22 of the sidejambs 16 and the ilange 30 of the sill 14 is cut away at its ends so asto engage the inner surface of the transverse walls 19 of the sidejambs, while the side jambs 16 have their transverse walls formed withend projections 36 as shown in Figs. 2, 3 and 5, which extend throughappropriate slots in the transverse walls 17 and 18 of the sill andlintel respectively and the extremities of the projections 36 arepressed or peened over so as to integrally connect the sill, lintel andjambs.

The lower ends of the sash frame engaging flanges 33 and 34 are cutsquare so as to provide abutting engagements with the sill transversewall 17. Likewise the inner and outer flanges 20 and 22 engage the uppersurfaces of the corresponding ilanges of the sill 14. Thus, with thesquare cut of the ends of flange 30 on sill 14, all parts are cut forright-angular relationship, one with respect to another.

The same right angular relationship of the side jarnbs 16 and lintel 15is maintained in a similar manner. Sash frame engaging flanges 33 and34, as best shown in Fig. 6 are cut at substantially 45 angles so as tohave mitered engagement. Trim flange 20 of each jamb frame is preferablysquare cut to engage the under surface of the same flange `of the lintel15. Outer trim flange 22 of each jamb is square cut below the upper endof transverse wall 19 thereof so as to fit against the lower edge ofilange 26 of the lintel.

Thus a most accurately dimensioned and truly squared frame of extremelystrong construction is produced at a minimum expense and yet attractivein appearance and l: when the preferred aluminum or its alloys isemployed,

a very light weight structure is provided.

For mounting the frame of the sash 11 in the window frame 10, as shownin Fig. 3 the transverse walls 19 are provided with apertures 37 midwaybetween flanges 33 and 34 and below the upper ends thereof. In theseapertures are mounted studs 38 each having a concentric bore 39 forreceiving a pivot pin 4i) as best appreciated in Figs. 4 and 5. The pins40 are provided with enlarged heads 41, with a kerf 42 in the outer faceof each head,.and the shank is provided with a transverse aperture orbore 43 in the same axial plane as the kerf so that the position of theaperture is easily determined when the pivot pin is positioned in stud38 for aligning the aperture 43 with a like aperture 44 in stud 38 forreceiving a cotter pin 45v to lock the pivot pin in place. Stud 3S is inshouldered en-V gagement with transverse wall 19 with a reduced endpor-V tion, as shown in Fig. 3, extending through aperture 37 in' thetransverse wall 19 and pressed or peened over into a locking engagementwith the outer surface of -this wall.

As best shown in Fig. 4, the horizontal transverse wall' 18 of thelintel has depression 47 formed therein preferably by a punchingoperation to upset a portion of the metal for receiving a conventionalsash latching member or catch 48 carried by the sash frame 11; a keeper49 mayv also be provided secured to the underside of the wall 18 t-oprovide additional engaging surface for the bolt 50 of the catch 48. .t

The vertical transverse Walls 19 of the side jambs are preferablyprovided with slots 51 adjacent their outer` edges for receiving screenlatch elements 52 as best shown in Fig. 7.

The window frame 10 of the window construction A is thus complete forinstallation and reception of the sashV frame 11 and screen frame 13which are detachable units of such construction that they may readily beapplied; after the sash frame is installed in a wall structure, and justas easily removed therefrom as desired when unlatched.

Sash frame 11 is also preferably fabricated from extruded metal stripspreferably aluminum or aluminum alloy and comprises, an upper rail orhead member 53, side stiles or members 54 and lower rail or bottommember 55, with these four members being miter fitted and preferablywelded at their corners to provide substantially` true angles and a verysturdy construction. The rail 53 and Stiles 54 are substantiallyidentical conformations of extruded metal and each rail and stile 53 and54 has la transverse wall 57 and spaced apart inwardly extending flanges56 and 58 normal thereto. The inner flanges 58 terminate in smalltransverse ilanges 61 the free ends of which engage the inner surface ofthe sash frame transparency or glass 12 and each llange 58 has anintermediate larger transverse llange 63 which substantially parallelsthe flange 61 and extends over the edges of the glass. The flanges 56and 58 extend to the inner faces of the walls 57. However, the bottomrail 55 differs from the rails and stiles 53 and 54 although it has atransverse wall 59 corresponding to the walls 57 and a transverselyshortened llange 6i) which takes the place -of the flanges` 58 since thefree lower edge `of the flange 60 abuts the place of the flange 56,which is provided but it has a shouldered free end to engage theshouldered free end of the flange 31 and provide a desirable connectionofsash and window frames, whereby there is` little if any penetration ofmoisture to the space between the flanges 30 and 31. As may be seen inFig. 4, in order to mount the sash frame 11 in the wind-ow frame 10 eachside stile 54 is provided with pivot lug 66 having an enlarged outerhead 67 and the shank 68 is` extended through a suitable aper ture inthe transverse flange 56 with its projecting portion peened to secure itin place. A link bar 69 pivots on each of these pivot lugs and has arecess therein into which the head 67 of the lug is received. When thesash frame 11 is mounted in place in the window frame 10, the upper endsof bars 69 which are correspondingly apertured and recessed forreceiving pivot pin 40, receive this pivot pin 40 positionedtherethrough and extended into aperture 44 in the stud 38 mounted on thetransverse wall 19 of the side member 16, and the c-otter pin 45 isinserted to detachably secure the window and sash frames together.

The pivotal axis for the swinging of the sash frame 11 is slightly abovethe horizontal plane of the bottom of the sash as defined by the loweredge of the flange 65 being determined by guide means 70 at each side ofthe sash frame 11. Each of the means 70 includes a slide member 71having a web portion 72 from the longitudinal edges of which extendparallel flanges 73 and 74, the first extending substantially the fulllength of the web portion 72 and the latter falling short of the bottomedge of the web portion. The members 71 are adapted to slide freelyalong the channels defined by the flanges 33 and 34 and adjacentportions of the side jambs 16 but they are adapted to cant and providefrictional gripping connections between the Window frame and sash frame,whereby they will maintain the sash frame at any desired tilted position(within limits) with respect to the window frame as will be described.These members 71 are apertured to receive the headed pivot pins 75 andtheir enlarged heads 76 are disposed within the channels of the members71. The Shanks of the pins are shouldered with reduced ends 77 extendingthrough apertures in the lower end portions of mounting strips 78, thereduced ends being peened to rigidly secure the pins in place. Anexpansion spring 79 is positioned between the faces of the members 71and the mounting strips 78. These springs 79 yieldably retain themembers 71 in their outermost positions on the pivot pins 7S so thattheir outer surfaces will frictionally engage the jamb transverse walls19 between flanges 33 and 34 thereof and also apply friction to thecanted members 71 in their engagement with the flanges thus tending tomaintain the sash in any desired adjusted open pos1t1on.

Mounting strips 78 are also extruded aluminum or alloy elements and,while quite rigid, have elasticity so as to cooperate with the springs79 in aiding the members 71 1n accomplishing their purposes. Thesestrips extend upwardly along the vertical transverse flanges of sidestiles 54 of the sash frame with their lower portions held in anoutwardly flexed position by pairs of rivets 80 extending therethroughand through the transverse walls 57 with tleir inner ends 81 peened overto secure the strips 78 in p ace.

In order to insert the sash frame 11 into the window frame lll, thepivoting link bars 69 being free at their upper ends, the sash frame 11is held yat an angle as shown in Fig. 6, then rst one member 71 isinserted between flanges 33 and 34 of side jamb 16 and then the othermember 71 between the corresponding flanges of the other side jamb. Thesash frame is then manually held in an inwardly tilted position as shownin Fig. 4 and the link bars 69 are connected by pivot studs 40 aspreviously described and as indicated in Fig. 5.

It will be noted that the pivotal connections of link bars 69 are quitefree, the bars acting as supports for the sash, raising the lower end ofthe same as it is swung inwardly as shown in Fig. 4 in which view thesash is swung to substantially its extreme limit.

The screen frame 12 likewise is preferably formed of extruded aluminumor allow strips. The strips are cut into four piecesk with mitered endsso as to form a rectangular `frame 82 with a screen edge receivingchannel 83 and a locking strip 84 which fasten screen material 8S to theframe. The framehas an upwardly and slightly outwardly extending flange86 on its upper part which flange ter1ninates in a Semi-cylindricalformation 87 for engaging over the rounded portion 29 at the upper endof the screen supporting flange 28 carried by the window frame lintel15. Thus the screen frame is mounted so as to swing outwardly from itsupper edge and, when drawn into engagement with the outer trim flanges22 of the window frame, its upper edge is held in tight engagement withthe Window frame elements by the` flange and cylindrical formation 87 incooperation with the rounded head portion of flange 28.

As shown in Fig. 7 the screen frame 82 is secured in its closed positionby means of the latch element 52 engaging slots 51 in the transversewalls 19 of the side jambs 16. This latch element 52 is part of a leverS9 pivoted at 90 to the screen frame and provided with an outwardlyextending, fingerpiece 91 by means of which the latch elements 52 may beswung into and out of engagement with slots 51 of the window jamb.

The edge portions of the walls 57 of the sash frame which face towardthe flanges 33 of the lintel and side jambs of the window frame togetherwith the narrow flanges 58 are provided with longitudinally-extendinggrooves or recesses 92, accommodating strips of weatherstripping 93.This Weatherstripping is vinyl plastic material and projects slightlyfrom the faces of the stiles 54 to engage the flanges 33 when the sashframe is in a closed position.

Various changes may be made to the form of the invention herein shownand described without departing from the spirit of the invention orscope of the claims.
